Informations

The Willis Tower, built as and still commonly referred to as the Sears Tower, is a 110-story, 1,450-foot (442.1 m) skyscraper in Chicago, Illinois. At completion in 1973, it surpassed the World Trade Center in New York to become the tallest building in the world, a title it held for nearly 25 years; it remained the tallest building in the Western Hemisphere until the completion of a new building at the rebuilt World Trade Center site in 2014. Willis Tower is considered a seminal achievement for architect Fazlur Rahman Khan. It is currently the second-tallest building in the United States and the Western hemisphere – and the 16th-tallest in the world. More than one million people visit its observation deck each year, making it one of Chicago's most popular tourist destinations. The structure was renamed in 2009 by the Willis Group as a term of its lease. As of April 2018, the building's largest tenant is United Airlines, which moved its corporate headquarters from the United Building at 77 West Wacker Drive in 2012, occupying around 20 floors. Other major tenants include the building's namesake Willis Group and law firms Schiff Hardin and Seyfarth Shaw. Morgan Stanley plans to move to the building in 2019 and become its fourth-largest tenant by 2020.

Informations

The Imperial Towers of Ontario were six of the earliest lighthouses built on Lake Huron and Georgian Bay, all constructed primarily of stone, by the Province of Canada. The origin of the designation Imperial is not certain, but some historians speculate that because the towers were public construction built under the colonial administration while Canada was a self-governing colony of Britain, the name would assure at least some funding from the British Empire's Board of Trade.All were built at a time when commercial shipping traffic was increasing on the Great Lakes between Canada and the U.S. because of new trade agreements and the opening of the Sault Ste. Marie Canal locks in 1855. The settlement of the Bruce Peninsula was already well underway at the time, also making the lighthouses timely as navigational aids for the boats and ships. All are currently operating as automated lights. All are currently operational as fully automated lights.
